A Shawnee, Oklahoma, family is looking for answers after their teenage son was the victim of a hit-and-run and suffered traumatic injuries.

Jacob Williams, 17, was walking home from a friend’s house last Wednesday when he was hit by a car, KFOR reported (video below)

“He remembers seeing some headlights coming and making sure he was in the grass, out of the way,” Jessica Williams, Jacob’s mother, told the news station. “He remembers waking up and yelling for help and cars are driving by and people were not stopping.”

Eventually, someone stopped and called paramedics to help Jacob. The teen was rushed to a trauma center.

The driver who hit Jacob fled the scene. Investigators only found pieces of a headlight in the grass and a tire mark on Jacob’s shoe.

“He’s in a lot of pain,” Williams added. “He’s frustrated and he’s angry and he’s scared.”

Jacob won’t be able to stand for at least three months, according to doctors.

“Please help me find whoever did this to me,” Jacob said in a video his mother sent to KFOR.

Jacob's father, Jim Williams, told the News-Star that his son is currently recovering at OU Medical Center with numerous injuries, including a broken pelvis.

The investigation is ongoing, but police believe the teenager was hit by a 1999 to 2002 model Chevy Silverado. The family is offering a reward for information that leads to an arrest and conviction.
